Uptake of Microparticles from Bio-Based Biodegradable Plastics by Aquatic Invertebrates

World sustainability series 2025

Summary

Researchers tested whether aquatic invertebrates take up microparticles shed from bio-based biodegradable plastics compared to conventional plastics like polystyrene, finding that organisms interacted with both types. This matters because biodegradable plastics are often promoted as safe alternatives, but if their breakdown particles are still ingested by aquatic animals they can enter food chains affecting humans.

Polymers

Microplastics are found in all terrestrial and aquatic habitats. They accumulate in marine environments and can interact with organisms, leading to deleterious effects. Microplastics from conventional polymers such as polystyrene (PS) or polyethylene (PE) are known...
